subdomain in glassfish

Question

Hi

I want to set up a virtual server for subdomain

my domain is redirected from pradyut.dyndns.org

to pradyut.dyndns.org/WebApplicationSecurity

using a virtual server whose default web module is WebApplicationSecurity I have used the string "${com.sun.aas.hostName},pradyut.dyndns.org" in the hosts of the virtual server

now to the question if someone enters "newa.pradyut.dyndns.org" how can i redirect to

pradyut.dyndns.org/WebApplicationSecurity/newa

or "*.pradyut.dyndns.org"

redirects to "pradyut.dyndns.org/WebApplicationSecurity/*"

Thanks

Pradyut
